Ding Keliang1,3),Liu Dajie2) and Hu Congwei2) 1)Institute of Geodesy and Geophysics,CAS,Wuhan 430077 2)Department of Surveying and Geo-Informatics, Tongji University, Shanghai 200092 3)Graduate School of CAS, Beijing 100039  
On the basis of basic adjustment model of GPS control network,the effect of GPS correlation between baselines on the adjustment result was analyzed theoretically and the formulea have been derived.The example has demonstrated that the correlation between GPS baselines should taken into account in the adjustment of high precision GPS control network,to reach the accuracy of few millimeter level.
